Any number will be a rational number when multiplied.0 multiplied by any real number is rational and so it will produce a rational number when multiplied.

If x is any non-zero number (rational or not), then since it is non-zero, 1/x is defined and x*(1/x) = 1 which is rational. So any non-zero number will produce a rational number when multiplied.


Thus any number will produce a rational number when multiplied.

Will 0.54732814 produce a rational number when multiplied by 0.5?

The product of two rational numbers is a rational number. All decimal numbers that terminate or end with a repeating sequence of digits are rational numbers. As both 0.54732814 (as written) and 0.5 are terminating decimals, they are both rational numbers.
